A Star Passed too Close and Tore Out a Chunk of a Protoplanetary Disk
When it comes to observing protoplanetary disks, the Atacama Large Millimetre/sub-millimetre Array (ALMA) is probably the champion. ALMA was the…
Rings in the Early Solar System Kept our Planet From Becoming a Super-Earth
A team led by Rice University has created a new model of planetary formation that answer how the Solar System…
This is How You Get Moons. An Earth-Sized World Just got Pummeled by Something Huge.
Titanic collisions are the norm in young solar systems. Earth's Moon was the result of one of those collisions when…
The Early Solar System Had a Gap Where the Asteroid Belt is Today

Protoplanetary Disks Throw Out More Material Than Gets Turned Into Planets
When a young solar system gets going it's little more than a young star and a rotating disk of debris.…
Astronomers see an Accretion Disk Where Planets are About to Form
Planet formation is notoriously difficult to study. Not only does the process take millions of years, making it impossible to…
